Title: Improvements in and relating to screws for flying machines of the helicopteral type
IPC: B64C27/615
Filed: 1920-06-28
Abstract: 146,257. Pateras Pescara, Raoul, Marquis of. June 28, 1919, [Convention date]. Helicopters; propelling.-Screw propellers for flying-machines of the helicopter type are provided with means for continuously and periodically varying the pitch during rotation for propelling, directing, and stabilizing the machine. If the pitch of the blades is decreased during haif a revolution and increased during the other half, the axial force exerted by the propeller will be displaced to a line parallel to the axis as at E', Fig. 9, and the machine will be tilted. The force represented by E' may be resolved into a vertical force V and a horizontal force H, the latter component producing a horizontal displacement of the machine. By a similar displacement of the line of action of the force exerted by the propeller, the machine may be restored from a tilted position. Apparatus for varying the pitch of the blades is shown in Fig. 4. A lever 1 is movable by the pilot in all directions about a universal joint 2 carried by the frame tube 3, the axis of which coincides with the axis of the screw. The lever 1 carries a universal joint 6, the outer part of which is provided with arms 7, supporting a ring 8. A ring 9 is rotatable on a ball bearing carried by the ring 8, and carries transverse bearings which support a pin 12 opposite each propeller blade. Each pin 12 carries a short radial tube 13 having external longitudinal ribs and an internal .screw thread of large pitch. The external ribs engage in grooves in the support 14, forming part of the member 15. A tube 17 is screw-threaded externally to engage with the internal screw in the tube 13, and by its longitudinal movement controls the pitch of the blade. If the lever 1 is inclined, the part 7, 8 will be displaced eccentrically but in its own plane, and will force, the member 13 to take up a periodic radial movement which induces a periodic rotary movement of the tube 17 and consequently a periodic variation of the pitch of the blades. The pitch may be varied by providing adjustable hinged ailerons in some or all of the blades, as in Fig. 3. or independently of the blades, or by providing flexible blades, or by providing ailerons which slide into the blades.

Abstract: 256,208. Schwitzer, A., and Erber, B., (trading as Ganz ctr Co., G.). July 31, 1925, [Convention date]. Making lamps; leading-in wires.-In making stems by pinching together the ends of a stem tube and of an arbor and embedding leading-in wires in the pinch, the wires are embedded before being cut from the supply wire which, by the act of withdrawing a pinched stem, is fed from the supply reels, and the wires are then cut at a point that leaves the ends of the supply wires located for insertion into a fresh stem tube. In the machine described, the stem parts are assembled in heads spaced around an intermittently rotating table. Each head comprises a socket 10 to receive the arbor rod, the socket being bored for the passage of the wires from the supply reels 7, and a gripper 12 to support the flare tube. The pinch is formed by jaws 4 operated through links 5 by a vertically moving rod 1. A gripper 40 carried by a vertical rack 36 then carries the pinched stem upwards, drawing the wires from the reels 7 after it. When the required lengths of wire have been drawn from the reels an adjustable stop 16 is raised, releasing a lever 17 from a catch 14. A spring 18 then moves the lever 17 through cam slots in cutters 13 to actuate the cutters and sever the wires. The vertical movement of the rack 36 is then arrested by a sliding member 37 obstructing a stop 38 on the rack. and the horizontal bevel-wheel 31 that operates the rack continuing to turn causes the rack to swing round horizontally with its pivoted carrier 33 and carry the finished stem to a delivery point. When the wheel 31 is reversed by the gear 27, 28, 29, a stop 39 on the rack engages the slide 37 to cause the rack to swing back until the slide 37 releases it to move downwards to pick up another stem. The stem gripped 12 is actuate. by a pair of racks 44.

Abstract: <PICT:0357172/III/1> <PICT:0357172/III/2> An apparatus for the continuous extraction of seeds and similar materials with a solvent consists of a rotatable drum having permeable walls, through which the extract is filtered.  A pre-treating drum may be provided in which the seeds are impregnated with the solvent and the saturated raw material is then fed axially into the filtering drum.  In a suitable apparatus, seeds are fed into a hopper 21, Fig. 1, and are passed by a screw conveyer 23 mounted on a hollow shaft 15, into a rotating drum 1 where they are impregnated with solvent admitted through an inlet 17 and perforations 19 in the shaft.  The materials are mixed by helical blades 9, and pass through a constriction 25 in which is mounted a screw 24, to a rotating filtering drum 11 mounted in a stationary casing 7.  The shaft 15 and the drums are rotated by separate driving means, whereby the duration of extraction treatment may be regulated.  The saturated material in the drum 11 is treated with a further amount of solvent supplied through an inlet 18 and perforations 20, and is mixed by blades 10.  The resulting extract filters through the permeable wall of the filtering drum 11, which consists of silk impregnated against moisture, and is finally drawn off through an outlet 8 to a distillation apparatus.  The residue in the drum is conveyed by a screw 26 to a discharge pipe 27, and may be again extracted, or pressed to yield a further quantity of extract. A pressing operation may also be inserted between the two drum treatments.  In a modification, Fig. 4, the filtering drum 2 is divided into drum cells 30 coupled together by constrictions 28. Raw material is conveyed through the cells by a screw and blades 10, and is treated in countercurrent with a solvent through the hollow shaft.
